Is there a way to limit duplicated warnings?

Is there a way to limit duplicated warnings, I've just seen a colleague working on a page which had 25,000 warnings, causing the page to become almost unusable. The issue was caused by a component that was repeated many times on the page, and so just a couple of accessibility issues with that component caused thousands of errors.

I appreciate fixing the accessibilty issue would solve this issue, but in the meantime development is severly affected as the warnings are slowing down the page significantly.
